Scientific context
Human HSP40/DnaJ proteins comprise a large protein family, members of which feature the J domain (named after the bacterial DnaJ protein) (1). The J-domain spans the first 75 N-terminal amino acids and is separated from the C-terminal by a glycine/phenylalanine-rich domain (2). Members of the HSP40/DnaJ family play diverse roles in many cellular processes, such as folding, translocation, degradation and assembly of multi-protein complexes. In particular, Hdj1, the first human HSP40/DnaJ protein identified, plays an important role in protein translation and folding, as well as in the regulation of HSP70 function (3). HSP40 stimulates the ATPase activity of HSP70 which in turn causes conformational changes of the unfolded proteins (4, 5). The HSP40-HSP70-unfolded protein complex further binds to co-chaperones Hip, Hop and HSP90 which leads to protein folding, or components of protein degradation machinery CHIP and BAG-1 (6). Some studies have shown that the difference between HDJ1 and type 1 DNAJ proteins including HDJ2 and yeast YdjI is the result of the possession of a zinc finger domain by the latter, which helps in the function of protein folding. (7, 8).

Test
StressMark antibodies supplies antibodies that are for research of human proteins. Mouse or mice from the Mus musculus species are used for production of mouse monoclonal antibodies or mabs and as research model for humans in your lab. Mouse are mature after 40 days for females and 55 days for males. The female mice are pregnant only 20 days and can give birth to 10 litters of 6-8 mice a year. Transgenic, knock-out, congenic and inbread strains are known for C57BL/6, A/J, BALB/c, SCID while the CD-1 is outbred as strain.

Properties
Human proteins, cDNA and human recombinants are used in human reactive ELISA kits and to produce anti-human mono and polyclonal antibodies. Modern humans (Homo sapiens, primarily ssp. Homo sapiens sapiens). Depending on the epitopes used human ELISA kits can be cross reactive to many other species. Mainly analyzed are human serum, plasma, urine, saliva, human cell culture supernatants and biological samples.
